A vibration isolation support consists of a rod A of radius R1 5
10 mm and a tube B of inner radius R2 5 25 mm bonded to an
80-mm-long hollow rubber cylinder with a modulus of rigidity
G 5 12 MPa. Determine the largest allowable force P that can be
applied to rod A if its deflection is not to exceed 2.50 mm.
